Collaborative study of the Toxicity Characteristics Leaching Procedure (TCLP)
Technical Report

OSTI ID:5319048
The United States Environmental Protection Agency has developed a new procedure, the Toxicity Characteristics Leaching Procedure (TCLP), to more effectively simulate the leaching of hazardous materials from waste disposed in an unsecured landfill. The procedure involves (1) an 18-hour extraction of a sample with sodium acetate solution and (2) the subsequent analysis of the leachate for metals, pesticides, semivolatile organics, and volatile organic compounds. To validate the method for all but the volatile organic analytes, 3 waste samples at 2 different pH levels were sent to 23 different volunteer government and commercial laboratories for extraction and analysis. For validation of the TCLP procedure involving determination of volatile organic compounds, two fortified waste samples were distributed to each participating laboratory.
